2009 Jeep Grand Cherokee ProblemsEngine Will not Start Due to Wireless Control Module Fault
A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.
Temperature blend and recirculation doors commonly fail, which can cause the AC modes not to change or the temperature to be different on the left and right sides. If replacing blend air doors, a recirculation door, a door link, or a sub-assembly housing, new heating, ventilation and AC (HVAC) sub-assemblies are available that improve reliability.
A Check Engine Light may illuminate indicating a "Cylinder #3 Misfire." This normally occurs in hot weather after the vehicle has been driven, parked for ten to twenty minutes, and then restarted. Heat from the exhaust vaporizes fuel inside the #3 fuel injector and causes the misfire. Installing an insulator sleeve normally lowers the temperature enough so the fuel will not vaporize.
2009 Jeep Grand Cherokee QuestionsGot reading of transmission solenoid what's estimated repair. What's the time frame I have to drive before car is not drivable (1 answer)
Car won't start one day and then the next day it does start. Car is not reliable and I'm worried I will be stranded.
The alert comes on earlier than it should. I use Mobil 1 which gives me more time between oil changes.
2009 Jeep Grand Cherokee RecallsThe Transfer Case may Shift into Neutral Unexpectedly
The 4-wheel drive transfer case can direct engine power to the rear wheels only, all four wheels, or in its neutral position, non at all. These vehicles are being recalled because the transfer case can shift into its neutral position without warning. If this were to occur, engine power would not reach any of the drive wheels and the vehicle could not move under its own power. Dealers will reprogram the final drive controller which governs the transfer case to correct this concern.
Wiring may be reversed on the steering column control module driver's air bag connector and cause the driver air bag not to deploy. If the driver's air bag does not inflate when needed, the risk of injuries to the driver is increased. Dealers will inspect the driver's air bag squib wires and replace the steering column control module. The recall began in May, 2009. The recall number is J13.
